R2-D2, the helmet. Created by Philadelphia-based artist and illustrator Jenn, this a do-it-yourself original. The force is strong with this one.

Jenn "sand-papered the crap" out of an old helmet, painted it, added the extra bit, and added a ton of clear coating.

"Initially, it was the ugly duckling of helmets," Jenn told website Geekadelphia. "It looked pretty jacked up before I did my fairy godmother thing to it. It was an odd, dark maroon color and it had been used as a rental helmet, so it had sustained damage over time. Long story short, I did a lot of spray painting and clear coating."
